To all wit/1711, it may concern:

dent of West Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements ing is a full, clear, and exact description.

This invention relates to machines for folding longitudinally-scored blanks of cardboard or similar material, said blanks being supplied with a deposit of gum to retain the opposite sides of the blank together, and thus from what may be termed cartons, which are collapsed andmay be stacked into piles ready for shipment; and my invention has for one of its objects the provision of an improved machine in which the blanks to be folded are placed in a pile at one end thereof and consecutively fed to the gumming and folding i g mechanism, which includes means for compressing the folded blank to cause a thorough .union between the gummed portions of the blank,andin which the folded blanks are finally stacked for transportation.

My invention has, furthermore, for its .object the provision of a blank-receiving device capable of storing a vastly-greater supply than heretofore and without interfering with the removal of the bottom blank on accountof undue or excessive friction caused by the weight of such additional blanks.

My invention has, furthermore, for its ob ject the improved construction and organization of the blades around which the sides of the blank are folded to form the carton, these blades being stationary while the blanks are consecutively brought into proper position longitudinally thereon by one or more conveyers and held against longitudinal movement therewith by a stopping device.

Furthermore, my invention includes as one of its features a series of feeding-rollerscooperative with the conveyer and serving at the same timeas flattening or compressingdevices to unite the gummed portion of the bilmk with its opposite edge portion orblank s e.

. My invention has also for its object the improved construction of the carton-discharging mechanism whereby the folded blanks are consecutively pushed upward against the weight of the upper pile of blanks, which serve in a measure to maintain each freshly gummed and compressed carton in perfectly fiat condition, and therefore allow ample time for the gum to dry or set.

Further objects of the invention will be found to be carried out in the particular construction and organization of some of the cooperating elements, as will. be hereinafter do scribed, and pointed out in the claims.

In the accompanying drawings, in which similar characters denote similar parts, Figures 1 and 2 together illustrate a top view of my improved machine. Figs. 3 and 4 together show a side view thereof, the front frame being removed. -Fig. 5 is a vertical cross-section on line a, Fig. 4, looking in the direction of arrow 5. Fig. 5 shows the action of the side-folders to complete the carton, and Fig. 6 is a section on line a, Fig. 4, looking in the direction of arrow 6 of that figure. V

In the drawings, 10 denotes a suitable frame supporting in bearings 11 the driving-shaft 12, carrying a pulley 13, to which movement may be imparted by any convenient source. Also mounted on this shaftis a bevel-gear 14, meshing with a similar gear 15, secured upon a longitudinally-disposed shaft 16, which constitutes the principal driving and actuating member for various operating parts of the machine.

In order to arrive'at a clear understanding of my improved machine, I will describe the several parts substantially in the succession with which they operate upon' the blanks, a

It is of chine by clamp-bolts Referring to Figs. 3 and i, it will be seen that the side guideposts 20 are provided with inwardlyp10 ]0eting steps or ledges 23 certain distances apart 5 vertically according to the height of said posts, and these ledges constitute one feature of. my

-invent.on, as above stated, their object being to serve as intermediate supports for the blanks and to relieve the bottom blank of any excess ive friction due to the weight of a great number of blanks above the same. In Fig. es

pecially the function of these ledges is clearly blank at a time the upper pile above the pins 2O 32 will contribute its lowest blank to the lower pile. The forward edges of the pile of blanks are supported on a roller 25, and a gage-plate 26, disposed in front of the pile, regulates the outlet-opening for what become successively the bottom blanks ofthe pile. Cllherearedges of the blanks rest upon plates 27, provided with slots 28 for the adjustment of blankengaging blocks 29 and secured upon a yoke 30,

to which reciprocatory movement on station- 3 ary longitudinally-disposed rods 3L may be imparted by a lever 32, fulcrumedat 33 on a bracket 34, depending from the machineframe and having at its upper end a link connection 35 with the yoke 30, while its lower 35 end is actuated by a pitman 36, operated by a cam 37, (see Figs. 1 and 5,) secured upon the driving-shaft 12. Asthc yoke 30 is moved forward by theu'iechanism just described the blank is engaged by.a pair of superposed feed- 4 rolls 4:041, mounted on shafts 42 t3, which are journaled in adjustable boxes carried by the frame 10, and one shaft, 42, is constantly driven by a sprocket it and chain 45, actuated by a sprocket t6, mounted on the shaft .19.

45 The roller 40 constitutes a pulley for an endless belt 47, which forms the blank receiving and transferringdeviee proper and which also passes over a roller 48, mounted on a shaft 49, journaled in a bearing carried by the frame 5 10. (,oiiperative with the carrier-belt 47 are the roller 41, above referred to, and also a se- -'ries of transfer-r0]lers 50, which are journaled on studs 5], held in frames 52, extending lat rally of the machine and mounted on a rock-shaft 53, which is journaled in brackets 54, secured to the frame. Proper oscillatory or rocking motion may be imparted to the shaft 53 by a. cam 55, (see Fig. 5,) secured l on the mainshaft 16 and actuating through a pitman 56 an arm 57, carried by 881d rocle shaft, so that said frames may be raised,

as indicated by dotted lines in that figure.

'As the blank is pushed forward and carried along by the belt/t7 a lineof gum is deposited 5 0n the underside of the flap eby a gumnnng Of course it is evident that as the l device ro '3perative with the pro: enroll 58, taking its supply from the gum-box (l. The

blank is now carried forward by the coaction l of the belt t7 and the transfer-rellers 5i.) until I its f' 'ont edge meets an obstruction in the t shape of a stop 59, which is preferably cured to and operated by the movement of the rock-shaft 53, so that as the roller-frames 52 are raised just previous to the arrival of the blank in its proper position to be acted upon by the side-folding mechanism to be hereinafter described, the stop 59 is simultal neously raised, and thus arrests the blanks l against progress beyond that point.

i in order to form a firm support for the 5 traveling belt t? at points where the rollers I 50 enter into eo 'iperation therewith, i provide below said belt and in vertical alinement with.

I said rollers a corresponding series of bolt supporting rolls (50, journaled in a chambered bar 61, secured with its left ends on a brace. l (32, extending externally of the maehine,while l its right end is supported on a bracket 63, car-- l ried by the frame 10. I Disposed below and above the line of travel of the blank, respectively, and near the lonf gitudinal folding-lines are one pair of blank- I supporting blades 6%, attached to the brace l 62, above mentioned, and for preventing the blank from bendingduringthe folding operation, and one pair of what may be termed vfoldingswords '65, rigidly mounted on a brace 66 and serving as edges around which the blan k-flaps are folded on the some lines r/- and Z) by the following mechanism.

I Journaled below the blank line of trz'ivel are I a pair of longitudinally-disposed shafts 7O ii, I having collars 72 T3 for holding the folding' l blades 74E 75,respcetirely,thelirst-named,Hot which folds the flap 0 around the outer edge l of the upper sword 65 in the manner shown I in Fig. 5 and which is operated by oscillatl ing the shaft -as, for instance, shown in i Fig. 6, in which said shaft is provided with a l pin-ion 76, engaged by a rack 77, receiving l proper reciprocation from a cam (not shown) I on the main shaft-16. I shaft 71 has a pinion 78, actuated by a rack l '79, also operated from the main shaft 16 to fold the flap 1? around the outer edge of the sword (35' subsequently to the hrst folding operation, and consequently to lay the edge l of the flap (Z on top of the now u jipermost and gumnied edge of the flap r, at the same 1' time pressing the flap ends together. The j blank is now practically in the form of a collapsed carton, and as the shaft 53 is now i rocked to drop the stop 55) out of the path of [the folded blank, at the same time again "tn'inging the rolls SO-downward, and thus l forcing the carton against the traveling be lt -17, the blank is withdrawn from the folding 's\v .n'ds 35 (35' and rondncted onto a stationary 'sum-iorl ronsisting in the present instance of l a HPl'iQm' of laterallyalisposed bars 80, having .l'na like manner the their front edges rounded, as shown in Fig. 4, to facilitate the longitudinal movementof the carton. l preferably employ, in conjunction with the supporting-lmrs 80, a corresponding series of rods 51 above the carton line of travel to hold the blank on the supports and guide it properly against a stop 82, adjust-ably held on the frame 10 to provide for different sizes of cartons.

Thus far the blank has been moving longitudinally of the machine. and its vpath is now changed into a lateral travel. The mechanism for effecting this movement comprises a p usher on, secured to the end of a spring-actuated arm .)1, which fulcrumcd at 92 and is operatcd by a cam 93, secured upon the shaft 16 and engaging a roller 94: on said cam. The folded blank is thereby carried between a pair of flattening-rolls 95 96, which are geared together and to which rotary movement is imparted by sprockets 97 98 and a chain 99. (See Fig. 2.) The carton, now finished, is delivered by the flattening-rolls 95 96' to a table 10o, having a vertical rcciprocatory movement to stack the cartons in a pile, to which each succeeding carton is added by being placed at the bottom thereof, can be clearly seen in Fig. 6. Here the table 100 is shown carried by an arm 101, fulcrumed at L02 on the frame. 10 and operated vertically by acam 103 on the shaft 16, engaginga roller 10 t, journaled on the pitman 105. The lateral movement of the cartons as they are thrown upon the table is limited by a pairof posts 106, and a pair of posts 107 are held on the framework of the machine to guide the blanks into a substantially even pile by serving as gagerods for the rear edges of the cartons, and inorder to permit the blanks properly to find their places between the rods 106 107 the latter are beveled at 107. (See Fig. 6.)

Pivotally secured on the posts 106 and 1707 are by-pass abutments 110,-the inner ends of which project into the path of the cartons and' are pushed upward thereby to permit the table to rise to the limit of its movement, (see ,dottcd lines, Fig. 6,) thereby raising the entire pile of cartons sufficiently to permit the abutments 110 to drop to their normal position again, so that when the table is now lowered all the blanks abovethe table will come to rest on the abutments [10 and the table l will return empty to its lowermostposition.

llaving thus described my invention, what I claim, and desire to secure by Letters latcut, is
